The warning signal light provides various colored light signals for independent use or use by an emergency vehicle. These light signals may include a stationary light, strobe light, revolving light, an alternating light, a flashing light, and an oscillating light. Additionally, the warning signal light may be capable of displaying symbols, reverse characters, or arrows.

The controller may further be adapted to regulate or modulate the power intensity exposed to the illuminated LED&#39;s to create a variable intensity light signal.

[0001] The present invention relates to a light emitting diode (LED)warning signal light having modulated power intensity for use byemergency vehicles and is based upon Provisional U.S. Patent ApplicationNo. 60/127,959, filed Apr. 6, 1999, which is incorporated herein byreference in its entirety.

BACKGROUND OF THE INVENTION

[0002] Light bars or emergency lights of the type used on emergencyvehicles such as fire trucks, police cars, and ambulances, utilizewarning signal lights to produce a variety of light signals. These lightsignals involve the use of various colors and patterns. Generally, thesewarning signal lights consist of revolving and oscillating lamps havingreflective back support members and colored filters.

[0003] Many problems exist with the known methods for producing warninglight signals. One particular problem with known light bars is theirreliance on mechanical components to revolve or oscillate the lamps toproduce the desired light signal. Additionally, these componentsincrease the size of the light bar or emergency lights which mayadversely affect the vehicles aerodynamic characteristics. Moreover,there is an increased likelihood that a breakdown of the light bar willoccur requiring the repair or replacement of the defective component.Finally, the known light bars require a relatively large amount ofelectrical current during operation. The demands upon the electricalpower system for a vehicle may therefore exceed available electricalresources reducing optimization of performance.

[0004] The most common light sources being used in light bars oremergency lights include halogen lamps or gaseous discharge xenon lamps.These lamps emanate large amounts of heat which is difficult todissipate from a sealed light bar or emergency light and which maydamage the electronic circuitry contained therein. In addition, theselamps consume large amounts of current requiring a large power supply orlarge battery or electrical source which may be especially problematicfor use with a vehicle. These lamps also generate substantialelectromagnetic emissions which may interfere with radio communications.Finally, these lamps, which are not rugged, have relatively short lifecycles necessitating frequent replacement.

[0005] Another problem with the known warning signal lights is the useof filters to produce a desired color. Filtering techniques produce moreheat that must be dissipated. Moreover, changing the color of a lightsource requires the physical removal of the filter from the light bar oremergency light and the insertion of a new filter. Furthermore, filtersfade or flake rendering the filters unable to consistently produce adesired color for observation in an emergency situation.

[0006] These problems associated with traditional signaling lamps areexacerbated by the fact that creating multiple light signals requiresmultiple signaling lamps. Further, there is little flexibility inmodifying the light signal created by a lamp. For example, changing astationary lamp into one that rotates or oscillates would require asubstantial modification to the light bar which may not be physically oreconomically possible.

[0007] The present invention relates to electrical lamps; moreparticularly, the invention relates to high brightness light-emittingdiode or “LED” technology which operate to replace gaseous discharge orincandescent lamps as used as automotive turn signals, brake lights,and/or back-up light sources.

[0008] Illumination lamps for automobile turn signals, brake lights,back-up lights, and/or marker lights/headlights frequently haveaccompanying utility parabolic lens/reflector enclosures which have beenused for utility warning signals or emergency vehicle traffic signaling.

[0009] These signaling devices as known are commonly referred to as“unmarked corner tubes,” “hide-a-way tubes,” or “dome tubes (“Hide-a-WayTubes” is a trade name of the Whelan Engineering Company).” Thesesignaling devices as known frequently utilize xenon gaseous dischargetubes or incandescent lamps as the illumination sources.

[0010] A problem with the prior art is the cost and failure rate of theknown “unmarked corner tubes,” “hide-a-way tubes,” or “dome lights.” Thefailure rate of these devices frequently results in significant amountsof “down time” for a vehicle to effectuate replacement. Further, anofficer is frequently unaware that a vehicle light is inoperativerequiring replacement. This condition reduces the safety to an officerduring the performance of his or her duties. In addition, the reducedlife cycle and failure rate of the known illumination devicessignificantly increases operational costs associated with materialreplacement and labor. A need, therefore, exists to enhance thedurability, and to reduce the failure rate, of illumination deviceswhile simultaneously reducing the cost of a replacement illuminationsource.

[0011] In the past, the xenon gaseous discharge lamps have utilized asealed compartment, usually a gas tube, which may have been filled witha particular gas known to have good illuminating characteristics. Onesuch gas used for this purpose was xenon gas, which providesillumination when it becomes ionized by the appropriate voltageapplication. Xenon gas discharge lamps are used in the automotiveindustry to provide high intensity lighting and are used on emergencyvehicles to provide a visible flashing emergency signal light.

[0012] A xenon gas discharge lamp usually comprises a gas-filled tubewhich has an anode element at one end and a cathode element at the otherend, with both ends of the tube sealed. The anode and cathode elementseach have an electrical conductor attached, which passes through thesealed gas end of the lamp exterior. An ionizing trigger wire istypically wound in a helical manner about the exterior of the glasstube, and this wire is connected to a high voltage power sourcetypically on the order of 10-12 kilowatts (kw). The anode and cathodeconnections are connected to a lower level voltage source which issufficient to maintain illumination of the lamp once the interior gashas been ionized by the high voltage source. The gas remains igniteduntil the anode/cathode voltage is removed; and once the gas ionizationis stopped, the lamp can be ignited again by reapplying theanode/cathode voltage and reapplying the high voltage to the triggerwire via a voltage pulse.

[0013] Xenon gas lamps are frequently made from glass tubes which areformed into semicircular loops to increase the relative light intensityfrom the lamp while maintaining a relatively small form factor. Theselamps generate extremely high heat intensity as well as light intensity,and therefore, require positioning of the lamps so as to not cause heatbuildup in nearby components. The glass tube of a xenon lamp is usuallymounted on a light-based pedestal which is sized to fit into an openingin the light fixture and to hold the heat generating tube surface in alight fixture compartment which is separated from other interiorcompartment surfaces. In a vehicle application, the light and basepedestal are typically sized to fit through an opening in the lightfixture which is about 1 inch in diameter. The light fixture componentmay have a glass or plastic cover made from colored material so as toproduce a colored lighting effect when the lamp is ignited. Xenon gasdischarge lamps naturally produce white light, which may be modified toproduce a colored light, of lesser intensity, by placing the xenon lampin a fixture having a colored lens. The glass tube of the xenon lamp mayalso be painted or otherwise colored to produce a similar result,although the light illumination from the tube tends to dominate thecoloring; and the light may actually have a colored tint appearancerather than a solid colored light. The color blue is particularly hardto produce in this manner.

[0014] Because a preferred use of xenon lamps is in connection withemergency vehicles, it is particularly important that the lamp becapable of producing intense coloring associated with emergencyvehicles, i.e., red, blue, amber, green, and clear.

[0015] When xenon lamps are mounted in vehicles, some care must be takento reduce the corroding effects of water and various chemicals,including road salt, which might contaminate the light fixture.Corrosive effects may destroy the trigger wire and the wire contactsleading to the anode and cathode. Corrosion is enhanced because of thehigh heat generating characteristics of the lamp which may heat the airinside the lamp fixture when the lamp is in use, and this heated air maycondense when the lamp is off to buildup moisture inside the fixture.The buildup of moisture may result in the shorting out of the electricalwires and degrade the performance of the emission wire, sometimespreventing proper ionization of the gas within the xenon gas dischargelamp.

[0016] Warning lights, due to the type of light source utilized, may berelatively large in size which in turn may have adverse affects uponadjacent operational components. In addition, there is an increasedlikelihood for a breakdown requiring repair or replacement of enlargedcomponents.

[0017] The known warning signal lamps generally emanate large amounts ofheat which is difficult to dissipate from the sealed light bar oremergency light area and may damage the electronic circuitry containedtherein.

[0018] Another problem with the known warning signal lights is the useof rotational and/or oscillating mechanisms which are utilized to imparta rotational or oscillating movement to a light source for observationduring emergency situations. These mechanical devices are frequentlycumbersome and difficult to incorporate and couple into variouslocations about a vehicle due to the size of the device. Thesemechanical devices also frequently require a relatively large powersupply to engage and operate the device to impart rotational and/oroscillating movement for a light source. Power consumption of electricalcomponents for an emergency vehicle is of primary consideration forvehicle operators.

[0019] Another problem with the known warning signal lights is theabsence of flexibility for the provision of variable intensity for thelight sources to increase the number of available distinct andindependent visual light effects. In certain situations it may bedesirable to provide a variable intensity for a light signal or amodulated intensity for a light signal to provide a unique light effectto facilitate observation by an individual. In addition, the provisionof a variable or modulated intensity for a light signal may furtherenhance the ability to provide a unique desired light effect forobservation by an individual.

[0020] No warning lights are known which are flexible and which utilizea variable light intensity to modify a standard lighting effect. Thewarning lights as known are generally limited to a flashing lightsignal. Alternatively, other warning signal lights may provide asequential illumination of light sources. No warning or utility lightsignals are known which simultaneously provide for modulated and/orvariable power intensity for a known type of light signal to create aunique and desirable type of lighting effect.

[0021] No warning signal lights are known which provide an irregular orrandom light intensity to a warning signal light to provide a desiredlighting effect. Also, no warning light signals are known which providea regular pattern of variable or modulated light intensity for a warningsignal light to provide a desired type of lighting effect. Further, nowarning light signals known which combine a type of light effect witheither irregular variable light intensity or regular modulated lightintensity to provide a unique and desired combination lighting effect.

[0022] It may also be necessary to provide alternative colored LED lightsources which may be electrically controlled for the provision of anydesired pattern of light signals such as flashing, oscillating,modulating, rotational, alternating, and/or strobe light effects withoutthe necessity of spatially inefficient and bulky mechanical rotationaldevices. In this regard, a need exists to provide a spatially andelectrically efficient LED light source for use on an emergency orutility vehicle which provides the appearance of rotation without thenecessity of a mechanical rotational device. In addition, a need existsto provide a spatially and electrically efficient LED light source foruse on an emergency vehicle which provides a flashing, modulated,oscillating, rotational, alternating, and/or strobe light effectswithout the necessity of mechanical devices.

[0023] In view of the above, there is a need for a warning signal lightthat:

[0024] (1) Is capable of producing multiple light signals;

[0025] (2) Produces the appearance of a revolving or oscillating lightsignal without relying upon mechanical components;

[0026] (3) Generates little heat;

[0027] (4) Uses substantially less electrical current;

[0028] (5) Produces significantly reduced amounts of electromagneticemissions;

[0029] (6) Is rugged and has a long life cycle;

[0030] (7) Produces a truer light output color without the use offilters;

[0031] (8) Reduces current draw upon an emergency vehicle power supply;

[0032] (9) Is positionable at a variety of locations about an emergencyvehicle; and

[0033] (10) Provides variable power intensity to the light sourcewithout adversely affecting the vehicle operator's ability to observeobjects while seated within the interior of the vehicle

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Light bar 70includes base 72, mounting means 74, cover 82, and warning signal lights10. Also included in light bar 70 are gyrators 90 used to impart motionto warning signal lights 10.

[0107] Referring to FIGS. 3 and 9, warning signal light 10 compriseslight support 12, light sources 30, controller 50 (shown in FIG. 11),and connecting portion 40 for attaching the warning signal light 10 tolight bar 70 or gyrator 90. The warning signal light 10 operates tocreate a warning signal for use by an emergency vehicle 104 byselectively activating light sources 30 using controller 50.Alternatively, warning signal light 10 may be formed of a solitary LEDlight source 30 at the discretion of an individual.

[0108] Light sources 30 are preferably light emitting diodes (LED's) andare generally arranged in aligned columns 32 and rows 34 as shown inFIG. 7 and 9. Each of the light emitting diodes (LED's) may haveshoulder portion 38 adjacent LED support 12 and dome 36. LED's 30 aresituated to be in electric communication with controller 50 and a powersupply, a battery, or power source. The use of light emitting diodes(LED's) to replace traditional halogen or gaseous discharge xenon lampsreduces heat generation, current draw, and electromagnetic emissions,while increasing lamp life and producing a more true output light color.

[0109] Controller 50, is used to selectively activate columns 32, rows34, or individual LED's 30, to create a constant light signal, a strobelight signal, a pulsating light signal, a flashing light signal, theillusion of a rotating or an oscillating light signal, a reversecharacter message, or images such as arrows.

Controller 50 generallycomprises microprocessor 52 and circuitry 53 and is preferably containedwithin, attached to, or an element of, LED support 12. It is envisionedthat controller 50 be programmed by an external controller 55 andpowered through cable R.

[0110] In a preferred embodiment, controller 50 generally comprisescircuit board 54 having microprocessor 52 attached to a low voltagepower supply, battery, or electrical source 56.

Transistors Q9 and QlO are in electronic communication withmicroprocessor 52, power supply, battery, or electrical source 56, andtheir respective columns 32.9 and 32.10 of LED's 30. Columns 32 of LED's30 are connected to transistors Q1-Q8, which are in turn connected tomicroprocessor 52 through resistors R1-R8. Microprocessor 52 is capableof selectively activating transistors Q1-Q8 to allow current flowingthrough transistors Q9 and Q-10 to activate the selected column 32 ofLED's 30.

[0111] In one embodiment, a rotating or oscillating light signal ispreferably established by the sequential illumination of entire columns32 of LED's 30 turning a desired number of columns on and thensequentially illuminating one additional column 32 while turning anothercolumn 32 off. Alternatively, the rotating or oscillating light signalmay be created by selectively activating columns 32 of LED's 30. Thefollowing algorithm may be used to provide a counterclockwise revolvinglight signal (FIG. 9):

[0132] A clockwise revolving light signal is created by performing steps1-19 in descending order then repeating the steps. An oscillating lightsignal is created by performing: (a) steps 7 through 16 in ascendingorder; (b) steps 7 through 16 in descending order; and (c) repeating (a)and (b).

[0133] A second embodiment of controller 50 provides a means foractivating LED's 30 individually to allow for greater flexibility in thetype of light signal created. This embodiment of the invention iscapable of displaying information in different colors or patterns.Depending on the size of the display, it may be necessary to scroll thesymbols or characters across the display to accommodate for a largervisual appearance. It is envisioned that the mir%or image of patterns,symbols, or characters could be displayed making the message easilyreadable by drivers viewing the signal in a rear view mirror. It is alsoenvisioned that this embodiment of the invention could display arrowsindicating a direction a vehicle is to travel or other images as shownin FIG. 2. In addition, combinations of signaling lights, directionarrows, and other information carrying signals or images, could bedisplayed simultaneously by the invention.

[0134] LED support 12 is envisioned to have several embodiments. Oneembodiment, shown in FIG. 9, consists of a panel 14 having front 16,back 18, top 20, bottom 22 and sides 24. LED's 30 are arranged on front16, with domes 36 extending therefrom, in columns 32 and rows 34. LED's30 are in electric communication with controller 50 which may becontained or sealed within LED support 12 to provide protection from theelements.

[0135] Another embodiment of warning signal light 10 is depicted in FIG.10. Here, the backs 18 of two panels 14 are attached together to allowfor a light signal to be produced on two sides. The two panels form LEDsupport 12. Alternatively, it is envisioned that a single panel 14having LED's arranged about front 16 and back 18 could be used as well.

[0136]FIGS. 6 and 8 show further embodiments of warning signal light 10.In FIG. 8, panels 14 are used to form an LED support 12 having foursides and generally shaped as squared. FIG. 6 shows panels 14 connectedto form an LED support 12 having three sides and generally shaped as atriangulated cylinder. In both embodiments, LED's 30 are arranged aboutthe fronts 16 of the panels 14. It is further envisioned that panels 14may be integral to each other.

[0137] Yet another embodiment of warning signal light 10, consists of aflexible panel 14 and controller 50 to allow LED support 12 to be formedinto various shapes. FIG. 5 shows LED support 12 formed into a circularcylinder. Further variations include the use of flexible panels 14 toform other shapes such as semicircles (FIG. 12) or to simply conform toa surface of an emergency vehicle (FIGS. 13 and 14). This embodiment isparticularly useful for undercover vehicles which generally position thewarning signal lights inside the vehicle. For example, panel 14 could beattached to the front, rear, or side window of an undercover police car.

[0138] It should be noted that numerous other shapes could be formedfrom panels 14 including those formed from combinations of flat, curved,and flexible panels at the preference of an individual.

[0139] In each of the embodiments discussed above, the array of LED's 30may comprise the same or differently colored LED's. Generally, eachcolumn may consist of a series of differently colored LED's. Controller50 may be configured to select the color LED to utilize in forming thelight signal. Accordingly, the user may select that a blue, red, white,yellow, green, amber, or combination thereof be used as the color oflight signal. Alternatively, the warning signal 10 may be formed ofindividual LED's 30 which may be selectively illuminated at thediscretion of an individual.

[0140] It is also envisioned that the controller 50 may control warningsignal lights 10 having multiple sides (FIGS. 5, 6, 8, and 10) such thateach side is capable of producing light signals that are independentand/or different from those produced by the other sides. For example,the squared cylinder warning signal light shown in FIG. 8 may produce orsimulate a red revolving light on first side 15. 1, while second side15.2 is simultaneously producing a blue oscillating light, while thirdside 15.3 is producing or simulating a stationary white light, and whilefourth side 15.4 is producing a white strobe light.

[0141] Another embodiment of warning signal light 10 is depicted inFIGS. 1 and 2 as light bar 70 which extends from driver side 100 topassenger side 102 of emergency vehicle 104. Cover 82 protects light bar70 from the elements. Each side of light bar 70 may have LED's 30 toproduce or simulate light signals on each side of emergency vehicle 104.Furthermore, controller 50 is used to create multiple light signals oneach side of light bar 70. For example, controller 50 may create asimulated revolving blue light positioned at front passenger side 102 oflight bar 70, oscillating white lights positioned at front driver side100, and yellow arrows there between. Additional or alternative lightsignals may be produced out the back 18 and sides of light bar 70. It isfurther envisioned that light bar 70 may consist of a single large arrayof LED's 30 across each side (not shown). This embodiment provides thelargest display and, therefore, is best suited to display desiredcombinations of warning lights and images.

[0142] Mechanical rotation and oscillation of warning signal lights 10about axis A is possible by way of attachment to gyrator 90 depicted inFIG. 3. Gyrator 90 mounted to light bar 70, generally comprises electricmotors 96 having cables 97. Gyrator 90 is configured to receiveconnecting portion 40 of warning signal light 10. Cable 97 is preferablyconnected to a power supply and either an external controller 55 orcontroller 50.

[0143] Gyrator 90 may be capable of rotating or oscillating warningsignal light 10 about a single or dual axis of rotation A. FIG. 3 showsgyrator 90 configured to rotate or oscillate warning signal light 10about a vertical axis A by way of motor 96.1 and oscillate warningsignal light 10 about a horizontal axis A by way of motor 96.2. Rotationor oscillation of warning signal light 10 about vertical axis A isaccomplished through direct attachment of connecting portion to motor96.1. Oscillation of warning signal light 10 about horizontal axis A isaccomplished by attaching swivel arm 99 to bracket 99.1 and post 99.2which is mounted to motor 96.2.

[0144] Alternative methods for imparting rotation or oscillation ofwarning signal light 10 may be accomplished through the use of electricmotors, toothed gears, and worm gears. In addition, maintainingelectrical communication between a power supply and an externalcontroller 55 with a revolving or oscillating warning signal light 10may be accomplished using brushes or other means without sacrificing theoperation of the warning signal light 10.

[0145] In another embodiment as depicted in FIGS. 13 and 14, emergencyvehicle 104 may include a front or rear windshield 106. The front orrear windshield 106 is generally angularly offset with respect to thevehicle at an approximate angle of 45 degrees. In this embodiment, themounting of a panel 14 of light sources 30 in flush contact with theinterior of a front or rear windshield 106 occurs through the use ofangular offsets 108 for the light sources 30 such that light emittedfrom the light sources 30 occur at a horizontal visual line (V) which issubstantially parallel to the plane of a vehicle and not at anapproximate angle of 45 degrees upward which corresponds to the anglefor the front or rear windshield 106.

[0146] In this embodiment, the ease of visualization of the light source30 is significantly enhanced by the downward angular offsets 108 whichposition the light sources 30 along parallel visual lines of sight (V).LED supports 12 or panels 14 may then be positioned in any desiredlocation within the interior of a vehicle in flush contact or proximateto the front or rear windshield 106. A suitable cable 97 is required toprovide electrical power for illumination of the light sources 30. Itshould be noted that the angle of incidence for the angular offsets 108may vary considerably dependent upon the make or model for the vehicleto include the warning signal lights 10.

[0147] It should be further noted that the warning signal light 10 maybe used with an automobile, motorcycle, snowmobile, personal watercraft, boat, truck, fire vehicle, helicopter, and/or any other type ofvehicle receptive to the use of warning signal lights 10. It should befurther noted that LED support 12 or panel 14 may be mounted to theinterior top dashboard of a vehicle proximate to the front windshield106 or to the interior top rear dashboard proximate to the rearwindshield 106 of a vehicle.

[0148] Mounting of a light support 12 or panel 14 to either the front orrear dashboards may minimize the necessity for inclusion of angularoffset 108 for the light sources 30. It should be further noted that LEDsupports 12 or panels 14 may be releasably affixed to the interior ofthe front or rear windshields 106 via the use of suction cups,hook-and-loop fabric material such as Velcro®, and/or any otherreleasable affixation mechanism at the preference of an individual. Anindividual may then adjust and reposition the location of the lightsupport 12 or panels 14 anywhere within the interior of a vehicle asdesired for maximization of visualization of the warning signal lights10.

[0149] In another alternative embodiment as depicted in FIG. 15, warningsignal light 10 may function as a remote, revolving, or stationarybeacon. In this embodiment, LED support 12 or panel 14 is preferablyreleasably connected to a transportable support 120 via the use of abracket. The transportable support 120 may be a tripod havingtelescoping legs or may be any other type of support as preferred by anindividual. In this embodiment, LED support 12 or panel 14 iselectrically connected to an elongate electrical extension cable 97which may include any desired adapter for electrical communication withthe electrical system of a vehicle. The remote light support 12 or panel14 may also include plug-in adapters for electrical connection to anydesired electrical power source other than a vehicle as is available.

[0150] The transportable support 120 may also include gyrator 90 asearlier described to provide a desired rotational or oscillatory motionfor warning signal light 10. A controller 50 having a microprocessor 52may also be integral to or in electrical communication with LED's 30 forthe provision of multi-colored lights, flashing, or moving characters asdesired by an individual. In this embodiment, the warning signal light10 may be physically separated from an emergency vehicle 104 any desireddistance to facilitate or enhance the safety of a potentially dangeroussituation necessitating the use of warning signal lights 10. Inaddition, it should be noted that a series of remote warning signallights 10 may be electrically coupled to each other for any desireddistance to again facilitate the safety of a situation necessitating theuse of warning signal lights 10.

[0151]FIG. 16 shows a perspective view of a xenon lamp 1. Xenon lamp 1has a base pedestal 2 which is typically formed of rubber, plastic, orother insulating material. Base pedestal 2 has a top surface 3 which maysupport a glass tube 4 which may have a looped curve such that an anodeend and a cathode end are each supported on a top surface. The anode andcathode ends may be sealed and respective electrical conductors 5 and 6may pass through the sealed ends and through the top surface 3. Atrigger wire 7 may be helically wound about the exterior surface of theglass tube 4 and the ends of the trigger wire 7 may be passed throughthe top surface 3 of the base pedestal 2 to form a third conductor onthe underside of the base pedestal 2.

[0152] Base pedestal 2 may have an upper cylinder portion 8 extendingfrom a lower shoulder all of which may extend above the top surface 3.The upper cylindrical portion 8 may include an upper shoulder 9. A glassdome (not shown) may be sized to fit over the xenon lamp 1 and glasstube 4 for resting on the upper shoulder 9. The glass dome may bepreferably made from a transparent or silicate glass material capable ofwithstanding heat stress. The outer diameter of the glass dome istypically about one inch which is sized to fit through the conventionalopening in a typical vehicle lamp fixture. The exterior glass domesurface typically has a much lower temperature during operation than theexterior surface of the glass tube 4 forming a part of the xenon lamp 1.The temperature drop between the glass tube 4 and the glass domefacilitates the use of coloring of the dome to provide a colored lamp byvirtue of the xenon light intensity passing through the colored dome.

[0153] The xenon lamp 1 is preferably aligned for insertion into aconventional opening 248 of a light reflector 260 (FIGS. 20 and 21). Thelight receptacle opening 248 in the light reflector 260 is typicallyabout one inch in diameter; and the glass dome and base pedestal 2 arepreferably sized to fit within the light receptacle opening 248. Thexenon lamp 1 in its final construction may include a cover plate (notshown) affixed over the bottom opening of the base pedestal 2 foraffixation to a light reflector 260 via the use of screws which passthrough the screw apertures 9.1. The anode, cathode, and trigger wire 7preferably traverse the base pedestal 2 and may include a plug 9.2 whichis adapted for engagement to a controller/power supply for a motorvehicle.

[0154] The light reflector 260 may be a conventional light reflector ofthe type found in vehicles having a clear plastic or glass lens cover.The glass or lens cover may be fitted over the front edge of thereflector 260 in a manner which is conventional with vehicle lamps. Itshould be noted that the light reflector 260 may be parabolically orother shaped at the preference of an individual. The light reflector 260may be mounted to a motor for rotation about a vertical axis. In thisembodiment the light source/replacement lamp 200 may be integrallyconnected or affixed to the reflector 260 for simultaneous rotationabout the vertical axis during use of the motor. Alternatively, thelight source/replacement lamp 200 may be fixed proximate to the verticalaxis where the light reflector 260 is rotated around the stationaryreplacement lamp 200 to provide for the visual appearance of arotational light source.

[0155] The glass domes as used with the xenon lamps 1 may be coloredwith any color as preferred by an individual including but not limitedto red, blue, amber, green, and/or white. It should be noted that thelight fixture incorporating the light reflector 260 may be a headlightfixture or a turn signal light fixture where the xenon lamp 1 is mountedinto the light reflector 260 on either side of a centrally-mountedhalogen light bulb which may be used as a headlight lamp. In this case,the light fixture could perform its normal function as a headlight andcould alternatively flash several additional colors, depending upon theneeds of the user. This configuration provides an emergency flashinglight construction which is wholly concealed within a normal head lampof a vehicle and is, therefore, not readily visible from outside thevehicle unless the lights are flashing. This construction may findapplication in an unmarked emergency vehicles such as might be used bysome law enforcement officers.

[0156] In operation, the LED replacement lamp 200 may be constructed asa replacement part for a conventional incandescent or xenon gaseousdischarge lamp. The standard mounting base 204 and LED support assembly212 may be sized to readily fit into the same light opening as anincandescent lamp would require, although it is apparent the electricaldriving circuit for the xenon lamp 1 may require modifications toaccommodate the gas discharge operating principles.

[0157] LED warning signal lamp 200 may be used in a variety of locationsabout a vehicle. It should be noted that the use of the LED warningsignal lamps 200 are not necessarily limited to positioning adjacent tothe head lamp or headlight, tail light, or turn signal illuminationdevices for an emergency vehicle 104. The LED warning signal lamp 200may be used as a rotational, pulsating, or oscillating reflector lightwithin the interior adjacent to a front, rear, and/or side window of avehicle.

[0158] It is also envisioned that the controller 50 may control warningsignal lights 200 independently of one another such that each warningsignal lamp 200 is capable of producing light signals which areindependent and/or different from those produced at another locationabout an emergency vehicle 104. For example, a front left turn signalmay produce a red colored light while simultaneously a front right turnsignal may produce an amber colored light and a right rear turn signalmay produce a green colored light and a left rear turn signal mayproduce a blue colored light. The controller 50 may then alternate thecolor of the light illuminated from the warning signal lamp 200 in eacharea as desired by an individual. Alternatively, the controller 50 maysequentially activate warning signal lamps 200 positioned about anemergency vehicle 104 to simultaneously produce a desired color oralternating sequence of colors. It should also be noted that thecontroller 50 may simultaneously illuminate all LED warning signal lamps200 to produce a flashing or strobe light which may be particularlyuseful in certain emergency situations. It should be further noted thatthe controller 50 may selectively illuminate individual LED warningsignal lamps 200 in any desired color, pattern, and/or combination asdesired by an individual.

In this embodiment the LED replacement lamp 200 includes astandard mounting base 204 which preferably includes a top surface 206.Extending upwardly from the top surface 206 is preferably an uppercylindrical portion 208 which includes an upper shoulder 210. Extendingupwardly from the upper shoulder 210 is preferably a support 212 whichincludes one or more LED lamp modules 213. The LED lamp modules 213 maybe of the same or different colors at the discretion of an individual. Awire 202 is preferably in electrical communication with the plurality ofLED lamp modules 213 to provide the electrical communication and contactfor the controller 50 to individually activate or illuminate LED lampmodules 213 as preferred by an individual. A plug-in connector 40 ispreferably coupled to the wire 202 for engagement to the controller 50and/or power source of an emergency vehicle 104.

[0160] The LED replacement lamp 200 is preferably adapted to bepositioned in a one inch light receptacle opening 248 (approximate size)which has been previously drilled into the backside of a reflectorassembly 260. The LED replacement lamp 200 is preferably used to replacea xenon gaseous discharge lamp or incandescent lamp as previouslymounted to a base and as inserted in opening 248 in a reflector assembly260. Illumination of one or more individual LED lamp modules 213, asmounted in the reflector assembly 260, enables the reflectorassembly/lens to take on the appearance of a warning signal or emergencysignaling lamp. The LED replacement lamp 200 preferably replaces thexenon gaseous discharge or incandescent lamp assemblies with highbrightness, long life LED technology.

[0161] Referring to FIG. 18, an incandescent lamp or quartz halogen H-2lamp is depicted and in general is indicated by the numeral 220. Theincandescent lamp assembly 220 is preferably formed of a standardmounting base 222. A vertical post 224 preferably extends upwardly fromthe standard mounting base 222. The incandescent light bulb 226 ispreferably mounted in the vertical post 224. The vertical post 224 mayextend below the standard mounting base 222 to provide for electricalcoupling with a wire 228 which preferably includes a standard pinconnector 230. The standard pin connector 230 is preferably adapted forelectrical communication to a power supply and/or controller 50 foractivation of the incandescent lamp assembly 220. The incandescent lampassembly 220 may be stationary or mounted in a rotational lightreflector 260 as desired by an individual. The light bulb 226 may be ahalogen H-2, 55 watt, lamp at the discretion of an individual.

[0162] As depicted in FIG. 19, LED replacement lamp 200 is adapted toreplace the incandescent lamp assembly 220 in a stationary or rotationallight reflector 260. The LED replacement lamp 200 as depicted in FIG. 19preferably includes a standard mounting base 234 and a vertical post236. It should be noted that the vertical post 236 may extend upwardlyfrom the standard mounting base 234 and may alternatively extend belowthe standard mounting base 234 at the preference of an individual. AnLED mounting area 238 may be preferably integral or affixed to the uppersection of the vertical post 236. The LED mounting area 238 preferablyincludes a plurality of individual LED module lamps 240 which may beindividually, sequentially, or illuminated in combination with otherlight sources at the preference of an individual.

[0163] The individual LED module lamps 240 are preferably in electricalcommunication with a wire 242 which includes an integral standard wireconnector 244. The wire connector 244 is preferably adapted to beplugged into a controller 50 or power supply. Communication is therebyprovided for selective illumination of the individual LED module lamps240. It should be noted that a group of individual LED module lamps 240are mounted in the LED mounting area 238. It should also be noted thatthe LED replacement lamp 200 is preferably adapted to replace theincandescent lamp assembly 220 or a xenon gaseous discharge lampassembly socket base of FIGS. 16 or 18. The purpose of the LEDreplacement lamp assembly 200 is to replace existing xenon gaseousdischarge and incandescent lamps with new LED technology whilesimultaneously utilizing existing standard bases in a standard lampenclosure. For example, an individual may choose to replace a halogen“H-2” 55 watt lamp with an “LED-2” lamp in an existing rotating lightfixture with no other structural modifications, yet achieving theadvantages of less power consumption, greater reliability, easierinstallation, less RF emissions (which reduces interference with radioor electronic equipment), cooler operating temperatures, simplifiedcircuitry, longer life, greater durability and duty capability, andsimultaneously providing pure and easier-to-see color light output.

[0164] As depicted in FIG. 20, a rotational light reflector 246 isdisclosed. The rotational light fixture 246 includes a reflectorassembly 260 having a standard opening 248. The incandescent lightassembly 220 is preferably positioned in the standard opening 248 forextension of the vertical post 224 outwardly from the reflector assembly260 for positioning of the light bulb 226 in a desired location. Lightemitted from the standard halogen light bulb 226 preferably reflects offthe parabolic-shaped reflector assembly 260 for transmission of light ina direction as indicated by arrows AA for visualization by individuals.Reflector assembly 260 and light source 226 may be rotated via the useof gears 250 and/or brushes which are preferably driven by electricalmotors not shown. In this manner, the rotational light fixture 246including the reflector assembly 260 may be rotated at any desiredvelocity as preferred by an individual.

[0165] As may be seen in FIG. 21, a rear or back view of the rotationallight fixture 246 is provided. As may be seen in FIG. 21, the lightsource is preferably positioned in the standard opening 248. The wire228 as in electrical communication with the light source and ispreferably connected via the standard pin connector 230 for electricalcommunication with a power source.

[0166] As depicted in FIG. 22, an alternative rotational light fixture252 is depicted. Rotational light fixture 252 preferably includes areflector assembly 260 which may be parabolic in shape for thetransmission of light along a common axis as depicted by arrows BB forvisualization by an individual. In this embodiment, the individual LEDmodule lamps 240 may be positioned to the front of the reflectorassembly 260 through the use of a frame 254. The frame 254 may beintegral or connected to a gear 250 as desired by an individual. Thegear 250 may be driven by a motor for rotation of the light fixture 252.It should be noted that the individual LED module lamps 240 arepreferably in electrical communication with a power source not shown.

[0167] It should be further noted that the rotational light fixture 252may also be adapted for oscillating or pulsating at the preference of anindividual.

[0168] An alternative replacement LED lamp 200 is depicted in FIGS.23-25. In this embodiment the LED replacement lamp 200 includes astandard mounting base 270. The standard mounting base 270 alsopreferably includes a plurality of teeth 272. The teeth 272 arepreferably adapted for mating coupling with gears integral to a motorand/or reflector 260, or rotational light fixture 246 to facilitaterotation and/or oscillation of the replacement LED lamp 200 at thediscretion of an individual. The standard mounting base 270 alsopreferably includes a top surface 274 opposite to the teeth 272.

[0169] An upper cylinder portion 276 is preferably adjacent to the topsurface 274. The upper cylindrical portion 276 preferably includes anupper shoulder 278. Extending upwardly from the upper shoulder 278 ispreferably a circuit board or support 280 which preferably includes oneor more LED illumination sources 282. The LED illumination sources 282may be of the same or different colors at the preference of anindividual. A wire 284 is preferably in electrical communication withthe LED illumination sources 282 to provide for communication andcontact with the controller 50 for combination and/or individualillumination of the LED illumination sources 282. A standard plug-inconnector may be integral to the wire 284 to facilitate couplingengagement to the controller 50 and/or power source for a vehicle 104.

[0170] The circuit board 280 is preferably adapted to have a first side286 and an opposite side 288. Preferably a plurality of LED illuminationsources 282 are disposed on both the first side 286 and the oppositeside 288 of the replacement lamp 200.

[0171] A glass dome or protector 290 is preferably adapted forpositioning over the circuit board 280 for sealing engagement to the topsurface 274 of the standard mounting base 270. The glass dome 290 may beformed of transparent plastic material or a transparent or silicateglass material capable of withstanding heat stress at the preference ofan individual. It should be further noted that the glass dome 290preferably protects the circuit board 280 and the LED illuminationsources 282 from contamination and from exposure to moisture during useof the replacement lamp 200. In this regard, the sealing lip 292 of theglass dome 290 preferably is securely affixed to the top surface 274 toeffectuate sealing engagement therebetween. The outer diameter of theglass dome 290 is preferably about one inch which is sized to fit withinthe conventional opening 248 in a typical lamp fixture or reflectorassembly 260.

[0172] The replacement lamp 200 depicted in FIGS. 23, 24, and 25 is alsoadapted to be positioned in a one inch light receptacle opening 248which has been placed into a reflector assembly 260. Illumination of oneor more individual LED illumination sources 282 as disposed on thecircuit board 280 enables the replacement lamp 200 to take on theappearance of a warning signal or emergency signaling lamp.

[0173] The replacement lamp as depicted in FIGS. 23, 24, and 25 mayalternatively permit the circuit board 280 to extend below the uppershoulder 278 to facilitate affixation and positioning relative to thestandard mounting base 270.

[0174] The controller 50 may regulate the illumination of the LED lightsources 282 individually, or in combination, to provide a desiredlighting effect for the replacement lamp 200. Also, the controller 50may illuminate the LED light sources 282 individually, or incombination, independently with respect to the first side 286 and theopposite side 288 to provide different light effects to be observed byan individual dependant upon the location of the person relative to thereplacement lamp 200. The controller 50 may also regulate the powerintensity to the LED illumination sources 282 to provide for a modulatedor variable light intensity for observation by an individual. It shouldalso be noted that the LED illumination sources 282 may be formed of thesame or different colors at the preference of an individual to provide adesired type of light effect for the replacement lamp 200.

[0175] In an alternative embodiment, the LED warning signal lamps 10 orLED replacement lamps 200 may be electrically coupled to a controller 50which in turn is used to provide a modulated power intensity for thelight source. A modulated power intensity enables the provision ofvarious patterns of illumination to create an illusion of rotation orpulsation for the warning signal lamps 10 or LED replacement lamps 200without the use of mechanical devices. In these embodiments, thecontroller 50 regulates and/or modulates the power supplied to thewarning signal lamps 10 or LED replacement lamps 200 thereby varying theintensity of the observed light. In addition, the controller 50 maymodulate the power supplied to the LED warning signal lamps 10 or LEDreplacement lamps 200 in accordance with a sine wave pattern having arange of 0 to full intensity. At the instant of full intensity, thecontroller 50 may also signal or regulate a power burst for observationby an individual. The controller 50 operating to regulate and/ormodulate the power intensity for the warning signal lamps 10 or LEDreplacement lamps 200 may establish the appearance of a rotational lightsource or pulsating light source without the necessity of mechanicalrotational or oscillating devices. The current draw upon the electricalsystem for an emergency vehicle 104 is thereby reduced. Spatial and sizeconsiderations for an emergency vehicle are also preferably optimized byelimination of mechanical, rotational and/or oscillation devices.

[0176] The controller 50 may also regulate the modulated power intensityfor the provision of a unique variable intensity light source. Theunique variable intensity light source is not required to cycle througha zero intensity phase. It is anticipated that in this embodiment thatthe range of intensity will cycle from any desired level between zeropower to full power as desired by an individual. A range of powerintensity may be provided between thirty percent to full power and backto thirty percent as regulated by the controller 50. It should befurther noted that an irregular pattern of power intensity may beutilized to create a desired type of light effect. In addition, thecontroller 50 may also sequentially illuminate adjacent columns 32 toprovide a unique variable rotational, oscillating, pulsating, and/orcombination variable rotational pulsating oscillating visual lighteffect. It should be noted that a pulsating light source may be providedthrough the use of a modulated power intensity to establish a varyingvisual illumination or intensity effect as desired by an individualwithout the use of rotational or oscillating devices. In this regard itshould be noted that the controller 50 may modulate the power intensityfor any combination of light sources 30 to provide a distinctive type oflight signal.

[0177] The use of a controller 50 to provide a modulated power intensityfor a light source may be used in conjunction with replacement lamps200, flexible circuit boards having LED light sources 30, paneledcircuit boards having LED light sources 30, light bars 70 having LEDlight sources 30, a cylindrical, square, rectangular, ortriangular-shaped circuit boards having LED light sources 30 and/or anyother type or shape of LED light sources including but not limited tothe types depicted in FIGS. 1-25 herein.

[0178] Further, the controller 50 may be utilized to simultaneouslyprovide modulated or variable light intensity to different and/orindependent sections, areas, and/or sectors of a light bar 70. Also, thecontroller 50 may be utilized to simultaneously provide modulated orvariable light intensity to different and/or independent sectors, areas,and/or sections of the forward facing side or rearward facing side ofthe light bar 70. In this embodiment it is not required that the forwardfacing and rearward facing sides of the light bar 70 emit the identicalvisual patterns of illuminated light sources 30. The controller 50 mayregulate and modulate the variable light intensity of any desiredsection of the forward facing side independently from the rearwardfacing side of the light bar 70. The controller 50 may thereby provideany desired pattern and/or combination of patterns of light signalsthrough the utilization of variable and/or modulated light intensity forthe forward facing side, and a different type or set of patterns and/orcombination of patterns of light signals having variable or modulatedlight intensity for the rearward facing side of the light bar 70 asdesired by an individual. It should be further noted that an infinitevariety of patterns and/or combinations of patterns may be provided forthe forward facing side and the rearward facing side of the light bar 70a the preference of an individual.

[0179] The use of the controller 50 to modulate the power intensity fora light source 30 to provide a a unique light signal may be utilizedwithin any embodiment of an LED light source 10, light bar 70, orreplacement lamp 200 as described herein.

[0180] It should be further noted that the modulation of the powerintensity for a light source 30 or replacement lamp 200 may be used inconjunction, or as a replacement of, the sequential illumination ofrows, columns, and/or individual LED light sources 30 to provide adesired type of unique light effect.

[0181] A modulated power intensity may be regulated by the controller 50to create a unique light signal within a single sector or in conjunctionwith multiple separated or adjacent sectors of light bar 70 for theprovision of any desired composite emergency light signal as preferredby an individual. All individual LED light sources 30 within a light bar70 may be exposed to incrementally increased modulated power intensityto provide for an incremental increase in illumination as regulated by acontroller 50. The incremental increase in power may continue until suchtime as maximum power is applied to an individual light source 30whereon a power burst may occur. The modulation of the power intensityfor the incremental increase in illumination of all LED light sources 30within light bar 70 thereby may provide the appearance of rotation of alight signal when observed by an individual. The power to the individuallight sources 30 may then be incrementally decreased at the preferenceof an individual. It should be noted that the power is not required tobe regularly incrementally increased or decreased or terminated. It isanticipated that a pulsating and/or modulated variable light intensitymay be provided by the controller 50 for regulation of the power outputfrom approximately thirty percent to maximum and back to thirty percentwhich affords a desirable type of pulsating modulated variable lighteffect.

[0182] It should also be noted that all individual LED light sources 30within a light bar 70 are not required to be simultaneously andincrementally illuminated to provide for the appearance of rotation. Forexample, a light bar 70 may be separated into one or more distinctsegments 76 which are formed of one or more columns 32 of LED lightsources 30. A particular segment 70 may be selected as a centralillumination band which may receive the greatest exposure to themodulated power source and, therefore, provide the brightest observablelight signal. An adjacent segment 78 may be disposed on each side of thecentral illumination band which in turn may receive modulated power ofreduced intensity as compared to the central illumination band. A pairof removed segments 80 may be adjacent and exterior to the segments 78,and in turn, may receive exposure to a modulated power source of reducedintensity as compared to segments 78. The number of desired segments maynaturally vary at the discretion of an individual. The controller 50 maythereby regulate a power source to provide a modulated or variable powerintensity to each individual segment 76, 78, or 80 to provide for aunique light effect for the light bar 70.

[0183] It should be further noted that light supports 12 may be flat andrigid, pliable, moldable, triangular, cylindrical, partiallycylindrical, and/or any other shape as desired by an individual providedthat the essential functions, features, and attributes described hereinare not sacrificed.

[0184] The provision of a modulated power intensity to the light bar 70may also be coupled with or in combination to the sequentialillumination of columns 32 as earlier described. In this situation, thelight signal may initially be dim or off as the individual columns 32are sequentially illuminated and extinguished for illumination of anadjacent column or columns 32. The power intensity for the illuminatedcolumn or columns 32 may simultaneously be incrementally increased for acombination unique rotational and pulsating modulated or variable lightsignal effect. In addition, the controller 50 may be programmed toprovide the appearance of rotation pulsation and/or oscillation at thediscretion of an individual.

[0185] Each individual LED light source 30 preferably provides an energylight output of between 20 and 200 or more lumens as desired by anindividual.

[0186] Each light support 12 preferably contains a plurality of rows 34and columns 32 of individual LED light sources 30. The supports 12 arepreferably in electrical communication with the controller 50 and powersupply. The supports 12 preferably are controlled individually to createa desired light signal for an emergency vehicle 104 such as rotation,oscillation, strobe, flashing, or stationary as preferred by anindividual. Each support 12 may be controlled as part of an overalllight signal or pattern where individual supports 12 may be illuminatedto provide a desired type or combination of light signal in addition tothe provision of a modulated or variable power intensity for the lightsource 30.

[0187] A modulated power intensity may be regulated by the controller 50to create the appearance of rotation within a single support 12 or inconjunction with multiple separated or adjacent supports 12 for theprovision of a composite emergency light signal as desired by anindividual. The light signal for each or a group of supports 12 may beregulated by the controller for the provision of a modulated powerintensity for an observable light signal. All individual LED lightsources 30 within a support 12 may be exposed to incrementally increasedmodulated or variable power intensity to provide for an incrementalincrease in illumination as regulated by a controller 50. Theincremental increase in power may continue until such time as maximumpower is applied to an individual light source 30 whereon a power burstmay occur. The modulation of the power intensity for the incrementalincrease in illumination of all LED light sources 30 within supports 12thereby may provide a desired visual light signal for observation by anindividual.

[0188] It should also be noted that the LED warning signal lamps 200 maybe incorporated into a light bar 70 which extends from a positionproximate to the driver's side 100 to a position proximate to thepassenger side 102 of an emergency vehicle 104. Cover 82 protects lightbar 70 from the elements. Each of the forward facing and rearward facingsides of light bar 70 may have LED's 30 to produce light signals on eachside of light bar 70. Furthermore, controller 50 is used to createmultiple light signals on each of the forward facing and rearward facingsides of light bar 70. For example, a controller 50 may create a bluelight signal positioned on the forward facing passenger side 102 oflight bar 70, oscillating white lights positioned at the forward facingdriver's side 100, and yellow lights there between. Additional lightsignals may be produced from the rearward facing side of light bar 70 atthe discretion of an individual where these light signals are the sameas or different from the signals emitted from the forward side 100.

[0189] Mechanical rotation and oscillation of replacement lamps 200about axis A is possible by way of attachment to gyrator 90 depicted inFIG. 3. Gyrator 90 mounted to a replacement lamp 200 generally compriseselectric motors 96 having cables 97. Gyrator 90 is configured to receiveconnecting portion 40 of replacement lamp 200. Connecting portion 40preferably includes a integral wire 202 to provide power forillumination of individual LED's 30. Cable 97 connects to a power supplyand either an external 55 or internal controller 50 at the discretion ofan individual.

[0190] Gyrator 90 may be capable of rotating or oscillating replacementlamps 200 about a single or dual axis of rotation A. FIG. 3 showsgyrator 90 configured to rotate replacement lamps 200 about a verticalaxis A by way of motor 96.1 and oscillate replacement lamps 200 about ahorizontal axis A by way of motor 96.2. Rotation or oscillation ofreplacement lamps 200 about vertical axis A is accomplished throughdirect attachment of a connecting portion to motor 96.1. Oscillation ofreplacement lamp 200 about horizontal axis A is accomplished byattaching swivel arm 99 to bracket 99.1 and post 99.2 which are mountedto motor 96.2.

[0191] Alternative methods of imparting rotation or oscillation toreplacement lamps 200 may be accomplished through the use of electricmotors, tooth gears, and/or worm gears at the discretion of anindividual.

[0192] It should be noted that each portion, section, sector, or area oflight bar 70 may be controlled as part of an overall light signal orpattern where individual sections or sectors may be illuminated toprovide a desired type of light signal including but not limited torotation and/or oscillation through the use of a modulated or variablepower intensity. Alternatively, the controller 50 may provide for therandom generation of light signals without the use of a preset patternat the preference of an individual.

[0193] Controller 50 may be used to selectively activate individualLED's 30 to create a constant light signal, a strobe light signal, aflashing light signal, an alternating light signal, and/or analternating colored flashing light signal for an emergency vehicle.

[0194] Controller 50 provides a means for activating LED's 30individually to allow for greater flexibility in the type of lightsignal created. This embodiment to the invention is capable ofdisplaying information in a variety of different colors or sequentialillumination of colors.
